At 10 ×104 Pa pressure and 300 K temperature, the volume of 0.09 mol CO 2 gas is 22.4 × 10−3 m3. What will be the volume of the gas if the pressure is decreased to 2 × 104 Pa ?
A
112.0 ×10−3 m3
B
37.4 × 10−3 m3
C
56.3 × 10−3 m3
D
28.1 × 10−3 m3
Explanation
According to Boyle's Law, formulated by Robert Boyle in 1662, the pressure and volume of a gas have an inverse relationship at a constant temperature. Using the formula P1V1 = P2V2, decreasing the pressure by a factor of five mathematically increases the volume to 112.0 × 10−3 m3.
